Another object of the invention is to provide a ventilating structure in which the parts are assembled simply by the interlocking feature thereof, it being unnecessary to use securing devices other than brackets adapted to be mounted upon thefloor of the corn crib or other structure. 7 I 3 An additional object isto provide a structure of this device which will be simple and inexpensive in manufacture, easy to set up or take down, positive in action, efficient and durable in service, and a general 1mprovement in the art.

With the above and other ObJBCtS and advantages in view, the invention consists in the details of construction and the arrange ment of elements to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a vertical crosssectional view taken through a corn crib equipped wlth the device, the device itself being likewise shown in section.

Figure 2 is a longitudinal sectlon taken on the line 2-2 of Figure 1.

Figure 3 is a detail cross sectional view taken through the ventilator structure.

Figure 4c is a detail sectional View showing the manner of mounting the same upon the floor. v

Figure 5 is a side elevation of one of the uprights. a

Figure 6 is a detall cross sectional view taken at the top of the ventilator structure, and c Figure 7 is a detail elevation of one of the spreaders.

Referring more particularly to the drawings, the letter A" designates, generally,a corn crib or the like, which maybe of any desired construction, but which is here, for the sake of illustration, represented as including a floor B mounted upon joists O sup,-

ported on sills 1)." Suitable uprights rise from springers F on the floor and carry transverse members G which; support the rafters H upon which the roofI is mounted. The usual slats J are secured to the various uprights E for defining the walls; As a mat{ ter of fact, there are n o limitations whatsoever as to the structure of the crib itself inasmuch as itmay'be anything desired, the

invention pertaining only to the 1 ventilating means to be described. A c i In carrying out the invention,.I provide,

a ventilating structure designated generally,

by the numeral lOfthis ventilator structure lncludlng spaced pairs of upright supporting brackets 11 which may,'in actual pract ce, be formed as'elonga ted metallic strips or bars cut at spaced intervals, as. indicated v at 12 ,to define'tong ue'members which are bent outwardly and inan angular shape to definesupporting brackets 13. Between the tongue 1 members or brackets 13, the uprights 11 are formedwith keyhole slots 14 vthrough which are inserted spreaders'15 of rod-like form provided at points spaced from their ends with grooves 16 defining reduced necks 17. The members 11 are held inthe proper spaced relation by inserting the spreaders 15 through the large portions of the key-hole slots Hand then sliding the spreaders downwardly so'that the neck portions 17 thereof will engage within the constricted portions of the key-hole slots. 7

Obviously, the spreaders will operate to hold the members 11 in spaced parallel relation. It may be desirable to provide a transverse member 18 betweenthe upper ends ofthe upright supports 11 as clearly indicated in order to provide a stronger bracing action.

For mounting the uprights 11 upon the floor B of the crib, use is made of angular brackets 19 which are nailed or otherwise secured upon the floor, as indicatedat 20, and which are formed with arms 21 having grooves therein defining constricted neck portions .22 engaging within key-hole slots 23 atthe lower ends of the uprights 11 as clearly indicated in Figure 4 of the drawings, Obviously, the key-hole slots at the lower portion ofthe members 11 must be reversed With respect to the key-hole slots 14;.

The ventilator structure further includes a plurality of superposed spaced horizontall extending strips 24: which simply rest Wit iin the angular bracket members: 13 as clearly indicated in the drawings.

Obviously, the ventilating. structure-= may" upon the number of ventilator structures employed, and Within eachcompartment the corn or the like maybe disposed with the assurance that there Will be ample Ventilationj afforded" topermit proper drying out and seasoning Without danger of rotting, molding onsouririg. It is really'believed that the construction, operation andadvantageswill be readily apparentto'one skilled in the art Without further explanation,"

thouglrit might he mentioned that it is ap parent that the device may be disassembled readily and stored in a compact form'so as to occupy but little space. This Will'also be of benefitduring transportation.

YWhile I have' shown and] described the preferred embodiment ofv the invention, it should be understoodthat I reserve the right tom-ake such changes in the-form, con;-

struction and arrangement of parts as will not depart from the spirit of the invention or the scope of the 'subyoinedclairhs,

Having thus described the invention, I c1aim:'- r v '1. In a corn crib or the like, a ventilating structure comprising spaced pairs of uprights, means for. mounting the uprights upon the floor of the corn crib or the like, .7

spreader means connecting the uprights for maintaining them in spaced parallel relation, anct'a plurality of vertically spaced stripscarried by the uprights, the uprights being provided with open topped angular bracket members torsupporti'ng said spaced strips: a
